C. won’t hear from                                                   D. haven’t heard from

 

【答案】

D

【解析】

試題分析：現(xiàn)在完成時(shí)用來表示之前已發(fā)生或完成的動(dòng)作或狀態(tài)，其結(jié)果的確和現(xiàn)在有聯(lián)系。動(dòng)作或狀態(tài)發(fā)生在過去　但它的影響現(xiàn)在還存在；也可表示持續(xù)到現(xiàn)在的動(dòng)作或　狀態(tài)。其構(gòu)成： have (has) +過去分詞。根據(jù)語境可知此句的含義是自從史密斯先生來到上海我從來沒有受到他的來信。因主語是I,故用助動(dòng)詞have not+過去分詞,故選D.

考點(diǎn)：現(xiàn)在完成時(shí)的基本構(gòu)成和用法.

點(diǎn)評(píng)： 注意現(xiàn)在完成時(shí)和一般過去時(shí)兩種時(shí)態(tài)的區(qū)分

(1)一般過去時(shí)的謂語動(dòng)詞用過去式，而現(xiàn)在完成時(shí)的謂語基本構(gòu)成是"助動(dòng)詞have /has +過去分詞"。 (2)一般過去時(shí)通常與表示過去的時(shí)間狀語連用。如：yesterday, last week, two years ago, just now, in 2002等； 而現(xiàn)在完成時(shí)則常與just, already, ever, never等副詞和these days, this week, since..., for...等表示一段時(shí)間的狀語連用。
